1. System Overview

The Tucano is the next development of the already successful SP900. New requirements for the Tucano were:

Higher accuracy and repeatability

Shorter cycle times

Faster product setup and change over times

Small foot print

Reduced maintenance costs

The Tucano was developed to handle a wide range of PCB sizes despite its small footprint of only 1.3m². With its extremely short cycle time of less than10 seconds and high accuracy of 12.5µm @ 6 sigma, this printer takes its place in the middle / high volume market. The mechanical design is optimise d for minimal maintenance costs.

The Tucano is designed to print solder paste, glue and other suitable mediums for stencil and screen printing.

1 Mechanic Overview

1.1 Structure

The basic stability of the Tucano is based on a welded structure. By using two independent structures to isolate the mechanics from outside influences which is successfully used on our Solar Printer. This gives a strong platform for fast cycle times, high accuracy and repeatability.

1.2 Table Mechanism

The table mechanism is designed for fast and accurate alignment. This is enabled by using ste pper motors with a high resolution. Additional is the whole table mechanism extremely strong designe d for excellent repeatability.

1.3 Fully Programmable Transport System

The new developed Transport System is designed for fast transport speed and a big range of products. For quick changeover and se t-up, the transport width of the conveyor is automatically set, but can also be adjusted manually. The transport system can be fully programmed for each product. Also is the transport direction, loading and unloading position free adjustable for all kinds of product lines.

The board-stencil alignment is done by moving the complete table in both horizontal axes and rotation. With the vertical motion, the snap-off distance and speed are controlled accurately and reliably.

The board stopper is fully programmable as it is integrated in the camera. Therefore, the board loading position is programmable too.

1.4 Stencil clamping system

For quick changeover, the automatic stencil clamping system is very helpful. Once the product is set up in the machine, next time the ste ncil will be loaded automatically.

1.5 Double Camera Vision System

The unique dual camera vision system uses a combination of store d and live images to align the board with the stencil. It can recognise standard board features or dedicated fiducials to provide perfect alignment each time.

The system is fast and flexible and features multipoint alignment to compensate for ste ncil stretch and board manufacturing variations. Alignment calibration and vision system training are fully automatic to minimise operator intervention.

With the fully programmable RGB-LED illumination the vision can use more than 16 Million different colours for illumination. Therefore, for every PCB or stencil the colour with maximum contrast can be selected. Therefore, for every PCB or stencil the colour with maximum contrast can be selected.

1.6 Camera Drive :

The Camera Drive is made out of a combination of Belt drive n for the y movement and ball screw driven for the x movement. All axes are controlled by powerful motors with high resolution Linear Encoders.

1.7 Print Table:

The rigid Table is fitte d with an extreme resistant surface provides a flat screen surface. Additional the grid supports the operator during placement of the Tooling Pins. (see software)

• Programmable print pressure using a an accurate motion control in combination with calibrate d springs

• Full programmable print speed in both directions

• Belt driven Print head for easy maintenance

1.9 Manual Tooling Grid

For manual tooling, the Tucano is equipped with a magne tic tooling grid. PCB Support Tooling can be placed accurately on the grid.

1.10 Under Stencil Cleaning System

The fully programmable under ste ncil cleaning system enables dry and wet cleaning cycles with or without vacuum (vacuum is available on Tucano-USC-V only).

Paper exchange can be easily done from front or back.

Solve nt exchange can be done by re placing the solvent bottle at the front of the machine.

3 Options

3.1 Post Print 2D Inspection of Board and Stencil

Post print inspection is a desirable function for integrate d, fully automatic production. The software can detect paste and printing errors for both the stencil and PCB. Automatic cleaning of the stencil is also possible using the inspection function.
